ESD Precautions

Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:



Do not remove modules or integrated circuits from their anti-static packaging until you are
ready to install them.



Before holding the module or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.



Wear a wrist-grounding strap, available from most electronic component stores, when
handling modules and components.
